2 Claims.

The present invention relates to a new and useful improvement in reciprocating loading pans of a type used in shaker conveyor lines in the mining of coal and positioned between the usual duck bill into which the coal is initially loaded and the conveyor chain for transporting coal to; mine cars, such loading pans serving to convey the coal from the duck bill to the conveyor chain and the invention has for its primary object to provide a discharge opening in the side of the pan together with a transversely curved baiiie or partition adjacent the opening and by means of which waste products may be discharged from the pan before reaching the conveyor.

In the mining of coal it is frequently necessary to separate and remove a large quantity of waste, such as slate, from the working face of the mine and it is the usual practice to load this waste material or slate onto mine cars, in the same manner that the coal is loaded, which means that such slate passes through the loading pan on its Way from the duck bill to the conveyor chain.

Such handling of the waste material incurs considerable expense and it is accordingly an object of the present invention to provide means for conveying the waste material to an unused part of the mine and discharging the material at that point and thus eliminate the labor and expense usually required for transporting the Waste material entirely out of the mine and away from the mine entrance in cars or the like.

A further object of the invention is to provide an attachment for such loading pans which may be easily and quickly removed therefrom when not in use so that the loading pan may be used in the usual manner in conveying the waste material from the mine working as well as the coal and loading the same into the mine cars.

A further object is to provide a. device of this character of simple and practical construction, which is efficient and reliable in operation, relatively inexpensive to manufacture and otherwise Well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein parts throughout, and in which:

Figure 1 is a fragmentary top plan view of a loading panshowing the waste removal attachment in position thereon.

Figure 2 is a, side elevational View.

like numerals refer to like 1 Figure 3 is a longitudinal sectional view taken substantially on a line 3-3 of Figure 1.

Figure 4 is a transverse sectional view taken substantially on a line 4-4 of Figure 1.

Figure 5 is a transverse sectional view taken substantially on a line 5-5 of Figure 2, and

Figure 6 is a perspective view of a transversely curved waste removal partition or baffle for the loading pans.

Referring now to the drawings in detail wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention. The numeral 5 designates a reciprocating loading pan of conventional construction and of a type forming part of the conventional shaker conveyor line equipment of a coal mine, the pan including outwardly projecting flanges 6 at the upper edges thereof. Since such shaker conveyor lines are well understood in the art, conventional illustration of the reciprocating loading pan is deemed sufiicient for the present purposes. At longitudinally spaced intervals the side walls of the pan are formed with one or more openings l in the opposite sides of the pan, the openings being normally closed by a door 8 hinged at one edge to the bottom of the pan by means of hinge members 9 and the free edges of the doors are formed with apertured lugs [0 adapted for aligning with similar lugs l I on the upper edges of the flanges 6 adjacent the sides of the openings 1.

Locking pins I2 are removably inserted in the aligned openings of the lugs l8 and II to secure the door in its closed position.

When the doors 8 are secured in their raised or closed positions the pan 5 is used in the usual manner for conveying coal from the loading duck bill to the loading conveyor forming part of the usual loading equipment of the mine and neither of which it has been deemed necessary to illustrate.

When it is desired to remove waste material, such as slate or the like, from the mine working, without loading such waste material onto the mine cars, one of the doors 8 is opened and a transversely curved baffle or partition I3 is placed in the pan with one end bent longitudinally to form a flange l4 extending outwardly at the outside of the pan at the rear edge of the opening 1, as shown in Figure 1 of the drawings, and the other end of the partition or bafi'le l3 has its upper edge bent downwardly to form a channel-shaped flange I 5 adapted for engaging the flange 6 at the opposite side of the pan.

A screw or pin I6 is threaded through the flange l5 and through an aligned opening in the flange 6 for securing the adjacent end of the v bafiie or partition l3 against movement in the pan when subjected to the force or pressure of the material travelling along the pan in the direction shown by the arrows in Figure 1 of the drawings and striking the partition to deflect the material outwardly through the opening 1 in the side of the pan.

A chain IT connects the pin or screw it to the partition 3 to prevent loss thereof. The baffle or partition i3 is curved forwardly from the rear edge of the opening i to guide the material toward the opening in the side of the pan for discharge therefrom onto the floor of an unused part of the mine.

It will be apparent that either or both sides of the pan 5 may be provided with one of the openings l and doors 8 and the baffle or partition I3 is interchangeably positioned at the rear edge of either opening to discharge the waste material from either side of the pan.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in the art. A more detailed description is accordingly deemed unnecessary. It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.

I claim:

1. A loading pan of the class described having an opening in-a side thereof, a; door adapted for direction.

2. A loading pan of the class described having an opening in a side thereof, a door adapted for closing the opening, a bafiie extending transversely in the pan and curved in a forward :direction, a flange at one end of the baiiie' adapted for engaging the outer side'o'f the pan atthe'rea'r edge of the opening, said pan having outwardly projecting flanges at itsupper-edge, and "a" channel-shaped flange on the uppered'ge oi the ba'ffle at its other end and adapted. 'for engaging the fia'nge at one side of the pan.
